Technically, from 10% of something to 35% of something is a 350% improvement or a 25 percent point improvement.

yes but people often conflate/confuse that... saying the delta in %'s... not % improvement. I agree with you, I'm attempting to point out how a small % increase is a huge actual improvement. This GP was saying that a 25% improvment in the efficiency of a rocket engine was not much to a layman.

Actually, from 10% of something to 35% of something is a 250% improvement. You already had the first 10%.
